Could you please be more specific, and what does this have to do with this thread?

I just saw what I linked for the first time today (though I had not looked at the BB.com page for a couple weeks or so). This is a thread about upgrading the OS and it is in the general discussion. If there are myths about different carriers and different OS versions then what/how/when does the link I posted do anything. Does it verify what carrier you are with? What does it do? I have not tried it, I know nothing about it, but I am sure it is listed as an upgrade and it is on the BB page not AT&T, Verizon, Tmo, etc. So what does it do, what myths are there about it and how it does whatever it does. What else do you request that I specify?
